Quality of Service for Wireless Technology in the WidexLink System
WidexLink wireless technology enables communication between two partners of a binaural pair
of CLEAR hearing aids and with their matched external devices. The requirements for the quality
of service (QoS) vary among the various components and their intended user scenarios.
For programming, these requirements include a BER (Bit Error Rate) better than 10-3, at a bitrate
of 212 kbits/s, a semi-duplex transmission with a required acknowledge, a transmission latency in
each direction (2x) and a receive-to-transmit mode (RX to TX) time. The data are saved in the
hearing aid even when transmission is interrupted.
Wireless Security Measures
Security of the wireless signals is assured through device system design that includes:
• Individual MAC address for each unit which is checked during each transmission.
• A built-in pairing table which specifies valid and legitimate pairing among units
• A proprietary Widex communication protocol which checks the package numbers
during each transmission.
• A Cyclic Redundancy Check (CRC) to check data validity and correct errors,
• A secure Bluetooth connection that is pass-key protected
• Authorized usage of programming software with single log-in

Warning to Hearing Aid Dispensers
A hearing aid dispenser should advise a prospective hearing aid user to consult promptly with a
licensed physician (preferably an ear specialist) before dispensing a hearing aid if the hearing aid
dispenser determines through inquiry, actual observation, or review of any other available information concerning the prospective user, that the prospective user has any of the following conditions:
(i) Visible congenital or traumatic deformity of the ear.
(ii) History of active drainage from the ear within the previous 90 days.
(iii) History of sudden or rapidly progressive hearing loss within the previous 90 days.
(iv) Acute or chronic dizziness.
(v) Unilateral hearing loss of sudden or recent onset within the previous 90 days.
(vi) Audiometric air-bone gap equal to or greater than 15 decibels at 500 hertz (Hz), 1,000 Hz,
and 2,000 Hz.
(vii) Visible evidence of significant cerumen accumulation or a foreign body in the ear canal.
(viii) Pain or discomfort in the ear.
Special care should be exercised in selecting and fitting a hearing aid whose maximum sound
pressure level exceeds 132 decibels because there may be risk of impairing the remaining hearing
of the hearing aid user. (This provision is required only for those hearing aids with a maximum
sound pressure capability greater than 132 decibels (dB).)
29
Important notice for prospective hearing aid users
Good health practice requires that a person with a hearing loss have a medical evaluation by a licensed physician (preferably a physician who specializes in diseases of the ear) before purchasing
a hearing aid. Licensed physicians who specialize in diseases of the ear are often referred to as
otolaryngologists, otologists, or otorhinolaryngologists. The purpose of medical evaluation is to
assure that all medically treatable conditions that may affect hearing are identified and treated
before the hearing aid is purchased.
Following the medical evaluation, the physician will give you a written statement that states that
your hearing loss has been medically evaluated and that you may be considered a candidate for a
hearing aid. The physician will refer you to an audiologist or a hearing aid dispenser, as appropriate, for a hearing aid evaluation.
The audiologist or hearing aid dispenser will conduct a hearing aid evaluation to assess your
ability to hear with and without a hearing aid. The hearing aid evaluation will enable the audiologist or dispenser to select and fit a hearing aid to your individual needs.
If you have reservations about your ability to adapt to amplification, you should inquire about the
availability of a trial-rental or purchase-option program. Many hearing aid dispensers now offer
programs that permit you to wear a hearing aid for a period of time for a nominal fee after which
you may decide if you want to purchase the hearing aid.
Federal law restricts the sale of hearing aids to those individuals who have obtained a medical
evaluation from a licensed physician. Federal law permits a fully informed adult to sign a waiver
statement declining the medical evaluation for religious or personal beliefs that preclude consultation with a physician. The exercise of such a waiver is not in your best health interest and its use
is strongly discouraged.
Children with hearing loss
In addition to seeing a physician for a medical evaluation, a child with a hearing loss should be
directed to an audiologist for evaluation and rehabilitation since hearing loss may cause problems
in language development and the educational and social growth of a child. An audiologist is
qualified by training and experience to assist in the evaluation and rehabilitation of a child with a
hearing loss.
